Shoe heel structure

ABSTRACT

A shoe heel structure includes a heel having a first hole with a thread thereon and a heeltap having a first screw. The first screw is being inserted into and engaged with the first hole. The wearer is able to remove an old heeltap from the heel and then assemble a new heeltap onto the same heel. In a further embodiment, the heeltap can be further guaranteed with a more secure fixation with the heel in the heel structure using a second screw and a second hole.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a shoe heel structure, in which a heeltap thereof may be replaced by a user without requiring any tools.

2. The Prior Arts

Shoes are aimed to provide protection and artistic effects to the feet. They are one of the most important items which people wear. However, when a person is walking with shoes on, the shoes will be gradually worn out and abraded due to its contact with the ground, particularly the heel thereof is most severe.

The shoe heel is directly contacted with the ground at the heeltap thereof, and thus the heeltap is a directly abraded portion of the shoe when the wearer walks on it. The common shortcomings and dangers of the worn out heeltap are as follows:

-   (1) The outer edge portion of the heeltap is more prone to abrasion,     thus forming a side-tilt. -   (2) The rear portion of the heeltap is to be prone to abrasion, thus     forming a rear-tilt. -   (3) One of the shoes is more badly abraded than the other, thus     forming an uneven height between the right and left shoes, thus     causing discomfort and potential injury to the wearer when walking.     Among all kinds of shoes suffering from abrasion-resulted damages,     the high-heeled shoes can be the most severe. When any of the above     cases occurs, a high-heeled shoe is apt to be tilted, and the ankle     of the wearer associated therewith could be sprained due thereto,     particularly a high-heeled shoe with a thin heel. To avoid any     injury to the wearer and to overcome the aforementioned shortcomings     and danger, the most direct method is to replace the heeltap when     necessary.

Referring to FIG. 1 and FIG. 2, a conventional high-heeled shoe is schematically depicted therein. As shown, a heeltap 103 of a shoe 100 has a post 104 extending upwards therefrom and a heel 101 of the shoe 100 has a hole 102. The post 104 has a diameter slightly larger than that of the hole 102 at the heel 101 of the shoe 100. During assembly, the post 104 is forced into the hole 102, so that the heeltap 103 is engaged with the heel 101. Although the heeltap of the conventional shoe can be replaced when necessary, it has the following disadvantage: When removing the old worn-out heeltap 103, a work bench, a clamping tool, and other auxiliary tools are required so that the old heeltap 103 and the post 104 thereof can be separated from the heel 103, and a new heeltap 103 can be engaged with the heel 101. In this case, although the new heeltap 103 is available to the wearer, she (particularly a woman wearing high-heeled shoes) has difficulty in making the self-repair work of the heeltap 103. Thus, an inconvenience issue is introduced.

In this regard, what is needed is a shoe heel structure which is easy to be replaced. To this end, the inventor of the present invention sets forth a new shoe heel structure, with which the problems existing in the prior art can be overcome.

SUMMARY OF THE INVENTION

It is, therefore, an objective of the present invention to improve upon the shortcomings for conventional engagement-type heeltap, in which a work bench, a clamping tool, and other auxiliary tools are required for removing or engaging the heeltap.

To achieve the objective of the present invention, a shoe heel structure comprises a heel having a first hole with threads thereon and a heeltap is attached with a first screw at the top, and the first screw, attached to the heeltap, is being inserted into and engaged with the first hole of the heel.

With use of the shoe heel structure according to the present invention, the heeltap can be assured of a secure fixation with the heel in the shoe by means of the engagement of the screw with the hole, and replaced when necessary by a wearer of the shoe without any tools required.

Other objectives, advantages and efficacies may be understood with reference to the description and drawings below.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, illustrate embodiments of the invention and together with the description serve to explain the principle of the invention. In the drawings:

FIG. 1 is a schematic view of a conventional engagement-type heeltap assembled with the shoe;

FIG. 2 is a schematic view of the conventional engagement-type heeltap shown in FIG. 1 thereof in an exploded view;

FIG. 3 is a schematic view of a shoe according to an embodiment of the present invention; and

FIG. 4 is a schematic view of the shoe shown in FIG. 3 with a heeltap thereof shown in an exploded view.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention discloses a shoe heel structure, which will be described in detail taken with the preferred embodiments with reference to the annexed drawings. However, the preferred embodiments are provided in an illustrative sense, but not intended to be limitative.

Referring to FIGS. 3 and 4, a plurality of schematic diagrams of a shoe in an assembled perspective view and in an exploded perspective view, according to an embodiment of the present invention, are illustrated. As shown, a shoe 10 comprises a heel 11. In the heel 11, a first hole 12 having a thread is formed therein. At a bottom portion of the heel 11, a heeltap 20 is provided to connect with the heel 11. A first screw 21 is formed to extend upwards therefrom the heeltap 20. To assemble the shoe 10, the first screw 21 of the heeltap 20 is inserted into and thus engaged with the first hole 12 of the heel 11. In this manner, the heel 11 is fixed as an integral part of the shoe 10.

In a preferred embodiment, the thread of the first hole 12 of the heel 11 is irregular. In addition, a hollow pad 22 may be sleeved onto the first screw 21 of the heeltap 20, so that the frictional engagement force existing between the first screw 21 of the heeltap 20 and the first hole 12 of the heel 11 is enhanced. In this case, the first screw 21 can be prevented from loosening from the heel 11.

In a further embodiment, a second hole 13 is additionally formed in the heel 11. The second hole 13 is laterally connectively opened to the first hole 12, and is inserted and assembled with a second screw 14. When the second screw 14 is engaged tightly into the second hole 13, the interior portion of the second screw 14 is abutted against the first screw 21 of the heeltap 20. In this manner, the heeltap 20 can be further prevented from loosening from the heel 11 by preventing the first screw 21 of the heeltap 20 from loosening and falling off.

In view of the above description, the wearer of the shoe having the heel structure of this invention is able to remove an old heeltap of the shoe and assemble a new heeltap to the shoe in a condition without necessity of any tool. Further, the heeltap can be guaranteed of a secure fixation with the heel. Therefore, the shoe heel structure does provide an excellent convenience to the wearer.

Although the present invention has been described with reference to the preferred embodiment thereof, it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention which is intended to be defined by the appended claims. 

1. A shoe heel structure, comprising: a heel having a first hole disposed therein and with a thread on the first hole; and a heeltap attached with a first screw at a top thereof, wherein the first screw is attached to the heeltap, inserted into and engaged with the first hole of the heel.
 2. The shoe heel structure as claimed in claim 1, wherein the thread of the first hole of the heel is irregular, and the first screw has a hollow pad sleeved thereon.
 3. The shoe heel structure as claimed in claim 1, wherein the heel further comprises a second hole, wherein the second hole is laterally formed, connected, and open to the first hole, and for receiving a second screw inside the second hole, and as the second screw is screwed tight, the interior portion of the second screw is abutted against the first screw of the heeltap for preventing the first screw of the heeltap from loosening and falling off.
